Filed: 1943-09-01
Abstract: 577,839. Time switches. LINDARS, H. Sept. 1, 1943, No. 14278. [Class 38 (v)] A control mechanism is arranged to regulate the ratio of operative to inoperative parts of the cycle of operating time of electrical apparatus. A helical-drive underfeed stoker 1 is operated when a relay 7 closes contacts 6 to complete the circuit of the driving motor 4. A disc 11, with an insulating operating rib 13, is rotated once a minute by a synchronous motor 48, closing contacts 8 to energize the relay 7, and subsequently opening contacts 10 in the relay holding circuit. The contacts 8 are fixed, but the contacts 10 are mounted on a disc 15, adjustable about a fixed spindle 21, with respect to contacts 8, and for timing the operative periods, by a knob 33 operating through a friction drive 36, 37, 15. Plate-like stops 42 on the disc 15 limit its rotation by abutting on the head of a fixed screw, Fig. 4 (not shown). An indicator gauge 29 driven by a wire rope 27 has its scale graduated to indicate the percentage feed of fuel. To allow of manual control of the fuelfeed, the control mechanism is made inoperative by a handle 60 actuating micro-switches 58 by means of a cam 59. An alternative construction of the control mechanism, Fig. 8, comprises an insulating disc 66 with a conducting segment 68, a conducting disc 67 with insulation 69, and fixed and angularly-adjustable contacts 70, 71. The operating element may alternatively comprise a drum or wiper arms.

Title: Method of and apparatus for locating and following sound emitting objects in water
IPC: G01S15/00
Filed: 1972-03-28
Abstract: 1360345 Position finding systems FRIED KRUPP GmbH 28 March 1972 [24 July 1971] 14575/72 Heading H4D In the location and tracking of a sound emitter in water, acoustic location of the emitter is effected by floating buoys whose locations relative to an aircraft are determined from the aircraft. An emitter 13, such as a transponder or ship is located at one apex of a location triangle DW derived by two buoys 11, 12. The emitter location, using a reference direction N, is radioed to an aircraft 14. The latter is located at the apex of a location triangle DF including the buoys whose locations are determined from the aircraft. In one embodiment (not shown) each buoy is located by radar, enabling determination of the triangle DF. By manoeuvering the aircraft to bring the displayed triangles DF, DW into coincidence, or coded details thereof into agreement, the aircraft is brought to a position above the emitter 13. Preferably, however, and as shown the aircraft does not determine the location triangle DF by means of an active radar method, but rather effects directional reception of the location data radioed from the buoys. To this end the aircraft 14 includes a receiver having a directional aerial 34 of frame construction. Alternatively, a ferrite or dipole directional aerial can be used. In more detail, Fig. 2, signals 5 from the emitter 13 are received directionally at each buoy 11 or 12 by an acoustic-electric transducer system 21 and fed to a location evaluator 27 which transforms the signals into directional information, for example into North-related bearings # 1 , # 3 . This information can, in addition, be coded to indicate from which buoy it arises. A data transformer 28 transforms the signals which are then transmitted as radio waves from an omni-directional aerial 23. At the aircraft 14, the received signals pass to a decoder 35 and thence to a radar position display 36 which may give a display of the two triangles DF, DW to be brought into coincidence or may give a digital indication of the angles #F, #W to be made identical. In a modification, the bearing angles # 2 , # 4  of the received radio waves are determined with respect to North. Thus, upon failure of one buoy, the bearing angle of the signals from the other buoy remains as reference information to permit replacement of the failed buoy. The derivation of the North-related location data is achieved by means of a data evaluation additionally provided in the aircraft. The number of buoys used is not limited to two.

Filed: 1921-05-28
Abstract: 186,387. Cloud, J. W., and Westing- house Brake & Saxby Signal Co., Ltd. May 28, 1921. Pressure-regulating valves controlled by pilot valves, particularly applicable for use as feedvalves on fluid-pressure braking systems. The main actuating-member is subject on both sides to low pressure when the main valve is in the closed position. The main slide valve 1 is carried by a spindle which is subject to high pressure on its lower end and acted on by a spring 24 and engages an actuating-piston 21 provided with packing-rings 29. A collar 9 on the spindle is arranged to engage a packing-washer 10 on a partition 5 separating the valve and piston chambers to prevent leakage when the main valve is in the closed position. The pilot valve 18, loaded by a spring 23, is carried by a tubular stem 17 adapted to work in a liner 16 and to rest at its lower end on a diaphragm 13 acted on by an adjustable spring 15. When the pressure acting on the diaphragm falls, the valve 18 is opened to allow high pressure in the chamber 22 - to pass through the passage 21 to the top of the piston to open the main valve. When the pressure is restored the valve 18 is allowed to close and the diaphragm draws away from the ported valve spindle to establish communication between the two sides of the piston. In a modification, the tubular stem is arranged to co-operate with a seat carried by the auxiliary valve.
